如何從MPMoviePlayerController獲取播放％進度

Question

我想知道用戶關閉視頻時視頻進展的程度。

所以對我有這樣的：

- (void) moviePlayerDidFinsh:(NSNotification*) notification 
{ 
    MPMoviePlayerController* moviePlayer = notification.object; 
    NSLog(@"FINISHED duration was:%f", moviePlayer.duration); 
} 

initialPlaybackTime和endPlaybackTime都縫是無用的。

Answer 1

MPMediaPlayback協議中有一個屬性currentPlaybackTime。

播放頭的當前位置。 （必需）

@屬性（非原子）NSTimeInterval currentPlaybackTime

％值= currentPlaybackTime /持續時間;

Answer 2

該物業是currentPlaybackTime（以秒爲單位）。

這隻有在MPMovieFinishReason等於MPMovieFinishReasonUserExited時纔有用。

NSDictionary* userInfo = [aNotification userInfo];  
MPMovieFinishReason finishReason = [[userInfo objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue]; 
if (finishReason == MPMovieFinishReasonUserExited) { 
     NSTimeInterval playbackTime = [moviePlayer currentPlaybackTime]; 
     // ... 
}
